> watching it jank around while some build spams 50k lines of output Add tmux to the equation and have some output like that simultaneously occuring in multiple visible windows within a single pane, and Terminal.app will also struggle, in my experience. To get a smooth experience on Mac, I had to use iTerm2 and enable the then-experimental GPU acceleration in the alpha version. I like to have my 'window management' for terminal stuff happen inside the terminal, so that my keybindings can live in my dotfiles and apply portably across operating systems. It's a great setup for me in terms of usability and efficiency, but it's also one that relies on great terminal performance. I was surprised to discover how much I'd taken terminal performance for granted!
